OFweek Lighting Network LED Bulbs are a new generation of lighting fixtures that use the shape of a bulb that people have become accustomed to. The internal light source is LED. Compared with traditional tungsten bulbs and fluorescent bulbs, it has: energy saving, environmental protection and service life. Long, fast response, high luminous efficiency, strong controllability, etc., has broad application prospects in the field of household lighting. In recent years, China's LED lighting technology has developed rapidly. LED bulbs are one of the most common lighting fixtures. The number of patent applications has increased substantially. As of December 31, 2014, the invention of LED bulbs disclosed in the CNABS patent database was disclosed. A total of 1,787 patents and a total of 4,456 utility model patents. The analysis of these patent data can reveal the current patent status and future development trend of LED bulb technology in China, and provide reference for technology research and patent application for related enterprises and individuals. 1. LED bulb lamp technology patent application status Based on the patent documents published in the China Patent Abstracts Database (CNABS), the patents relating to LED bulbs published before 2014 (including 2014) are counted. The statistics focus on the structure and parts of LED bulbs. Through the reasonable use of IPC classification numbers, keywords and other retrieval methods, the invention and utility model patents involving LED bulb technology are first checked, and then noise reduction is finally obtained. A relatively accurate statistical sample is used, and on this basis, the finalized patent literature is analyzed in depth. 1.1 The patent application situation over the years The distribution of patent applications in the calendar year is shown in Figure 1. The number of applications has increased significantly year by year in 2007 and 2013. The reasons are as follows: 1 With the continuous improvement of China's economic development level, the protection of intellectual property rights in the whole society The consciousness is gradually improved. 2 The Chinese government has implemented a series of industrial support policies for the green lighting industry, such as the “Eleventh Five-Year Urban Green Lighting Project Planning Outline” promulgated by the Ministry of Construction in 2006. In 2007, the multi-ministerial committee jointly issued the “Efficient Lighting Product Promotion Financial Subsidy Fund Management”. Interim Measures, the Outline of the Green Lighting Plan for the Eleventh Five-Year Plan, promulgated in 2011. 123
